ATL / WTL / STL

Because the design of MFC means you can use ordinary Win32 calls inside an MFC application but not the other way round.

Definitely, it helped at least in half a problem. The rest lays in XML entities like &_amp_; (without underscore). I think I should treat them manually. Generally, mbstowcs won't help. I had to use win32 function where I can define more encoding standards.

This is not a C++ issue. You are much more likely to get a useful response in the Database Discussion Boards - CodeProject[^].

As I said, the AdditionalLibraryDirectories path is where it looks for the .LIB file at link time. At run time nothing in your project settings have any meaning to the Windows operating system. When the program loader starts your executable it looks for all the .DLL files that are required. It first looks in the directory where the executable is loaded from, and then in all the directories listed in your system's PATH environment variable. So you either copy your dll into the directory where the .exe file resides, or add its location to the PATH variable.

OK, I see that now. And I see why he did that. I often have a difficult time seeing the obvious. Thank you for pointing that out and taking the time to reply. Thank you for your time If you work with telemetry, please check this bulletin board: www.irigbb.com

MTU size dictates this... To figure out the system MTU size at run-time, in Linux use getsockopt() with IP_MTU. ip(7): IPv4 protocol implementation - Linux man page[^] Windows has a similar call but not sure if the MTU option is readily available. Keep in mind that every device that the packet touches will impose it's own MTU size restrictions on it and you can't necessarily control all of them (depends on setup of course). In another words, even if your device doesn't fracture a packet, another one down the line may choose to do so. There are ways to do "mtu" discovery to find the max size transferrable. Just something to be aware of.

I presume you mean something like: void ShowError(DWORD dwError, PWSTR pszMessage, int maxMessageSize ) { if (dwError == 0) { dwError = GetLastError(); } if (FormatMessage( FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_IGNORE_INSERTS | FORMAT_MESSAGE_MAX_WIDTH_MASK, // don't include line breaks NULL, // no source message dwError, // message identifier MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), // default language pszMessage, // address of message buffer maxMessageSize, // size of user supplied buffer NULL // optional parameter list ) == 0) { // unknown error code swprintf_s(pszMessage, maxMessageSize, L"Error code: %d (0x%X)", dwError, dwError); } } Which you call by: WCHAR szMessage\[512\]; ShowError(nErrorCode, szMessage, \_countof(szMessage)); wcout << "Exception: " << szMessage << endl;
